I signed up for NOAH coin, as ATAIX seems to be one of the few sites to have it listed (big supporter of the NOAH project), but I noticed there isn't a huge variety of coins to trade for yet. Seems the platform is new, so I'm sure this will change over time, but dogecoin was one of my favorites to trade for on other platforms among some others, and I'm wondering if anybody has any idea if there's plans to list it. Also, where can I stay up to date with stuff like this in the future?
